Let's get this math done. We have 437 and we're going to multiply it by 25. This is the same as taking 437 and adding it to itself 25 times.
Step 1: 0 + 437 = 437
Step 2: 437 + 437 = 874
Step 3: 874 + 437 = 1311
Step 4: 1311 + 437 = 1748
Step 5: 1748 + 437 = 2185
Step 6: 2185 + 437 = 2622
Step 7: 2622 + 437 = 3059
Step 8: 3059 + 437 = 3496
Step 9: 3496 + 437 = 3933
Step 10: 3933 + 437 = 4370
Step 11: 4370 + 437 = 4807
Step 12: 4807 + 437 = 5244
Step 13: 5244 + 437 = 5681
Step 14: 5681 + 437 = 6118
Step 15: 6118 + 437 = 6555
Step 16: 6555 + 437 = 6992
Step 17: 6992 + 437 = 7429
Step 18: 7429 + 437 = 7866
Step 19: 7866 + 437 = 8303
Step 20: 8303 + 437 = 8740
Step 21: 8740 + 437 = 9177
Step 22: 9177 + 437 = 9614
Step 23: 9614 + 437 = 10051
Step 24: 10051 + 437 = 10488
Step 25: 10488 + 437 = 10925

So, 437*25 = 10925
